I THOMPSON M. OONNER AND THEODORE M. OONNER, OF RICHMOND, INDIANA,ASSIGNORS TO THE CONNER AND MATHER MANUFACTURING COMPANY,

OF SAME PLACE.

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 322,350, dated July 14,1885. Application filed March 20, 1885. (No model.)

To all} whom it may concern.-

Be it known that we, THoMrson M. CoNNER and THEODORE M. CONNER, bothresidents of Richmond, in the county of Wayne and State of it appertainsto make and use the same, refer-.

ence being had to the accompanying drawings, which form a part of thisspecification, and in I which-- a d y Figure 1 is a perspective view ofa rollerskate provided with our improvement. Fig. 2 is a longitudinalvertical section through one of the brackets. Fig. 3 is a verticalcrosssection of the same on line as m, Fig. 2; and Fig. 4 is ahorizontal section on lines 3 y, Figs. 2 and 3.

Similar letters of reference indicate corresponding parts in all thefigures. I Our invention has relation to that class of roller-skateshaving a yielding cushion interposed between the bracket secured to thebottom of the board and the bracket having the rollers; and it consistsin the improved construction and combination of parts of the same, ashereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the bracket securedto the board, which brackethas thetwo perforated lips, B B,

' through which extends the pin 0, upon which the upper fiat end of theroller-supporting bracket D is pivoted, and the said upper brackct, A,is formed with a longitudinal slot, E, in 1ts upper plate, and with arecess, F, in its long lip above the perforation.

G is a stirrup shaped frame, which fits around the yielding block H,having its inner end piece, I, bearing against the block inside of theshort lip of the upper bracket, and having its side pieces'bearingagainst the sides of 5 the block, while its outer end piece is formedwith a screw-threaded perforation, J, which accommodates a set-screw, K,fittingwith its inner end in the recess F.

Theinner end piece, I, of the stirrup-shaped frame is provided with anupwardly-projecting lug, L, which slides in the 'slot E in the upperbracket, and with a downwardly-projecting lip,M,' which bears againstthe end of the elastic block, and the outer end piece, N, is providedwith a downwardly-proj ecting lip, O, which bears against the outer sideof the head 1? of the pin Owhen the frame is adjusted in its properposition, holding the pin and securing it.

It will be seen that the upwardly-projecting lug upon the inner endpiece will guide the frame as it is drawn against the elastic block bymeans of the screw, and drawing the frame against the block willincrease its tension, the side pieces of the frame confining the block.The downwardly-proj ecting lip upon the inner end piece of thestirrup-shaped frame will raise the said end piece by bearin g againstthe top of the lower bracket,so as to hold the outer end piece of theframe down, thus causing the downwardly-proj ecting lip upon the outerend piece to project down over the head of the pivotal pin, keeping itin its place.

When it is desired to withdraw the said pin, the set-screw is screwedout, when the outer end of the frame may be raised, and thus allow thepin to be withdrawn; and it will be seen that by tightening theset-screw the inner end piece of the frame will compress the rubberlaterally, so as to increase its vertical tension.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States 1. In a roller-skate, thecombination of the upper bracket having the lips confining the elasticblock endwise, the elastic block, the lower bracket confining theelastic block from below, and a stirrup-shaped frame surrounding theelastic block bearing against one end and the sides of the same, andhaving means, substantially as shown, for tightening its inner. endpiece against the end of the block, as and for the purpose shown and setforth.

2. In a roller-skate, the combination of the elastic block, the upperbracket having the downwardly-proj ecting lips,the lower bracket Wpivoted with'its upper flat end between the said lips, a stirrup-shapedframe bearing with. its inner end and with its side pieces against theend and sides ofthe block, and a screw 5 passing through the outer endpiece of the frame and bearing with its inner end against 7 the lip ofthe upper bracket, as and for the purpose shown and set forth.

3. The combination of the upper bracket, A,

10 having the lips B B, and formed with the longitudinal slot E, theelastic block, the lower bracket pivoted between the lips of the upperbracket, and the stirrup-shaped frame having the upwardly-projecting lugL and, the set-screw K, as and for the purpose shown and set forth.

4. The combination, ina roller-skate, of the upper bracket, A, havingthe lips B B, the longest one of which is provided with the recess F,the elastic block, the lower bracket fitting between the lips B, thepivotal pin 0, passing through the perforated lips B and having head 1?,and the stirrup-shaped frame G, having its inner end piece bearingagainst the elastic block, and having the lip 0, projecting downwardfrom its outer end piece,

and the screw K, passing through the said end piece and fitting into therecess F, as and for the purpose shown and set forth.

'5. In a roller-skate, the combination of the upper bracket having theperforated lips BB, the longer one of which has the recess F above theperforation, the elastic block, the lower, bracket pivoted between theperforated lips, the pivotal pin 0, having head P and passing 5 throughthe perforated lips and through the upper end of the lower bracket, andthe stirrup-shaped frame formed with the downwardly-projecting lip Mupon its inner end piece and with the downwardly projecting lip 0 uponits outer end piece, and having the setscrew K, fitting with its innerend into the recess F, as and for the purpose shown and set forth.

In testimony that we claim the foregoing as 5 our own we have hereuntoaffixed our signatures in presence of two witnesses.
